摘要
笔者以800 kV GIS(gas insulated switchgear)高压开关设备的抗震性能为研究对象,采用模态分析理论对设备进行动力特性分析,得到了结构自振频率和振型。分别利用反应谱理论和时程分析理论对结构进行地震动特性分析。通过反应谱分析和输入天津波、EI-Centro波、taft波的动力时程分析,讨论了这两种分析方法结果上的一致性与局限性。并根据几种不同地震波对高压开关设备的不同影响,得出相对于taft波振幅和持时较小的天津波对设备产生破坏作用最大;经过对频率调整,具有相同幅值的两种EI-Centro波形,由于特征频率存在差异,EI-Centro2对于结构所产生的影响显著超过EI-Centro1。
Aiming at the seismic performance of the 800 kV gas insulated switchgear(GIS),the modal analysis theory is adopted to analyze its dynamic characteristics. Hence the structural natural frequencies and the mode shapes are obtained. By using the theories of response spectrum and time history analysis, the vibration characteristics of the structure are analyzed. Through the response spectrum analysis and the dynamic time history analysis with Tianjin wave, EI-Centro wave, and Taft wave,the consistency and limitation of the results from both analysis methods are discussed. According to the effects of different seismic waves on the GIS equipment,conclusions are drawn that compared with taft wave, Tianjin wave with smaller amplitude and shorter duration imposes bigger destructive effect; and the EI- Centro2 wave with higher/lower frequency exerts bigger impact on the structure than the EI-Centro1 wave with same amplitude and lower/higher frequency.
